    Is there any way to calculate the speed an object given work done and object's mass. I kno W=mad or .5mv^2.

    work done on an object = change in kinetic energy

    work = 0.5m(vfinal)^2 - 0.5m(viniitial)^2

    if vinitial = 0

    work = 0.5m(vfinal)^2

    just solve for vfinal in this equation.
